摘要
Abstract
The aerodynamic configuration characteristics of the starship,the control strategies of the front and rear wings,and typical manned moon landing missions with the starship are analyzed by means of a numerical simulation method.The performance parameters and aerodynamic configuration of the starship are modeled by inversion,and the starship is designed with a low mass-to-drag ratio aerodynamic shape.The results show that,different from the traditional shuttle reentry,and the terminal velocity during reentry is low,and the starship attitude can be effectively controlled with the front and rear wings and engines at both small and large angles of attack.Moreover,with the innovative combined technology of aerodynamic airfoil and engine reverse thrust,the starship can achieve horizontal reentry and vertical landing by means of making full use of the aerodynamic deceleration.A preliminary analysis is carried out on typical manned moon landing missions with the starship,and the results show that the required launch times for the starship on-orbit replenishment is still much large.With the orbital delivery scheme,the starship has the capacity of fulfilling a global transport mission within one hour.关键词
